Bacterial motility on a surface: many ways to a common goal.
TLDR
This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.Abstract:
When free-living bacteria colonize biotic or abiotic surfaces, the resultant changes in physiology and morphology have important consequences on their growth, development, and survival. Surface motility, biofilm formation, fruiting body development, and host invasion are some of the manifestations of functional responses to surface colonization. Bacteria may sense the growth surface either directly through physical contact or indirectly by sensing the proximity of fellow bacteria. Extracellular signals that elicit new gene expression include autoinducers, amino acids, peptides, proteins, and carbohydrates. This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.read more

TL;DR: The results indicate that G. lucidum and its high molecular weight polysaccharides may be used as prebiotic agents to prevent gut dysbiosis and obesity-related metabolic disorders in obese individuals.
Journal ArticleDOI
Hydrodynamic attraction of swimming microorganisms by surfaces
TL;DR: It is demonstrated theoretically that hydrodynamic interactions of the swimming cells with solid surfaces lead to their reorientation in the direction parallel to the surfaces, as well as their attraction by the closest wall, which compares favorably with measurements.
Journal ArticleDOI
Rhamnolipids: diversity of structures, microbial origins and roles
TL;DR: A wide diversity of rhamnolipid congeners and homologues that are produced at different concentrations by various Pseudomonas species and by bacteria belonging to other families, classes, or even phyla are found.
Journal ArticleDOI
Microbial interactions within the plant holobiont.
TL;DR: The fundamental role of microbe-microbe interactions (prokaryotes and micro-eukaryotes) for microbial community structure and plant health is discussed and a conceptual framework illustrating that interactions among microbiota members are critical for the establishment and the maintenance of host-microbial homeostasis is provided.
Journal ArticleDOI
Collective motion and density fluctuations in bacterial colonies.
TL;DR: This work reports simultaneous measurements of the positions, velocities, and orientations as a function of time for up to a thousand wild-type Bacillus subtilis bacteria in a colony, demonstrating that bacteria are an excellent system to study the general phenomenon of collective motion.

Biofilm Formation as Microbial Development
TL;DR: The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.
Journal ArticleDOI
Biofilms as complex differentiated communities.
TL;DR: It is submitted that complex cell-cell interactions within prokaryotic communities are an ancient characteristic, the development of which was facilitated by the localization of cells at surfaces, which may have provided the protective niche in which attached cells could create a localized homeostatic environment.

Flagellar and twitching motility are necessary for Pseudomonas aeruginosa biofilm development

TL;DR: The isolation and characterization of mutants of Pseudomonas aeruginosa PA14 defective in the initiation of biofilm formation on an abiotic surface, polyvinylchloride (PVC) plastic are reported and evidence that microcolonies form by aggregation of cells present in the monolayer is presented.
